Reflexive verbs are also used without reflexive pronouns, but in that case they're not considered reflexive verbs. For example, in 'I cut myself with a knife by accident', 'cut myself' is reflexive, but in 'I cut the onion with a knife', 'cut' is not reflexive.

Hello everyone,
I have just studied "reflexive verbs in english" in my grammar book and then I came here. I have been learning english by myself for about one year. During this time I read and wrote a lot of sentences which have reflexive verbs without knowing they are "reflexive verbs". But I could understand their meaning from the context.

My mother language is Turkish, and Turkish has also reflexive verbs and pronouns as a concept. Of course grammar rules are different from english but if your mother language has this grammar rule as a consept (I think it has definitely has) you already use them.
